Abstract

Banana tree trunks have a high cellulose content which is around 63-64% but the life cycle is relatively short, this makes the banana tree trunks have the potential to be used as raw material for making carboxymethyl cellulose (CMC). Carboxymethyl cellulose (CMC) is a cellulose derivative compound that is biodegradable, colorless, odorless, non-toxic, granules or powder that dissolves in water. Of the two types of CMC from banana stone stems and cotton banana stems in Riau Central Sumatra, it is necessary to do a laboratory study of the effect of CMC from banana stems on filtration loss and thickening time in drilling cement. To determine the effect of two CMC samples of banana stems, CMC was made and drilling cement was tested at the Petroleum Engineering Laboratory - Riau Islamic University. The process of making CMC from banana stems starts from sample cutting, boiling, washing, compaction, sample bleaching, alkalization process, CMC synthesis, neutralizing, drying the sample and filtering the sample to become CMC powder. After that filtration loss and thickening time tests were carried out on drilling cement with a concentration of 0%, 0.2%, 0.6%, 1% and 1.4%. From filtration loss testing with additive CMC banana cotton stem, the results were said to be feasible, namely at a concentration of 1% 246.46 ml / minute and 1.4% 23.46 ml / minute. Additive CMC banana stone at a concentration of 1% 240.99 ml / minute and 1.4% 230.89 ml / minute. In thickening time data testing obtained from CMC banana rock additive with a concentration of 0.2% 104.17 minutes, 0.6% 116.28 minutes, 1% 119.05 minutes, 1.4% 125 minutes. For additive CMC, banana cotton stem is obtained with a concentration of 0.2% 102.04 minutes, 0.6% 111.11 minutes, 1% 116.28 minutes and 1.4% 121.95 minutes. It can be seen from the results that it has been obtained that each addition of concentration indicates that every CMC additive can slow down the cement suspension hardening process.
